The Pedersoli Lightning is considered one of the very few WORKING Colt Lightning reproductions. I had a chance to test one in 44-40 (44 WCF) caliber, a cartridge I really love. The bore of the Pedersoli gun is Pedersoli Match Grade broach rifled barrel, so it is 100% up to competition standards. I have my blackpowder load developed for my Uberti 1873 Winchester. So here is the way I reload my cartridges and here is the test results of the first 50 m shooting session.
